Keno Drawing Procedures

KENO drawings will take place seven days a week from 5:04 a.m. to 1:00 a.m. The drawings take place approximately 3 minutes apart.

A computer-driven, random number generator will select the winning numbers for each drawing. The random number generator will only select winning numbers after receiving confirmation from the Lottery's computer system that betting for that drawing has been closed. The Lottery will select twenty (20) numbers out of a field of eighty (80) numbers ranging from number one (1) to number eighty (80).

More Specifically

There are two computer systems involved in a KENO drawing. The primary computer takes all bets. Attached to this main computer is a random number generator that is constantly shuffling 80 numbers around. Once the betting is closed, the primary computer asks the random number generator for 20 numbers. At that moment, the primary computer knows the 20 winning numbers and graphically displays them on the KENO monitors at agent locations.

The random number generator is independent of the primary computer and has no way of determining which bets the primary computer accepts. The sole purpose of this generator is to continuously shuffle numbers and provide the primary computer with a set of winning numbers when asked.
